Apple Newton Connection Utilities (for Macintosh) - Manual (Page 3)

Connecting with a serial cable
You use a serial cable to connect your Newton device to the printer or modem
port on the back of your computer. If you don’t have a serial cable, you can
purchase one from an authorized Apple dealer. The cable has mini DIN-8
connectors on both ends.
To connect with a serial cable, follow these steps:
1 Make sure both your computer and your Newton device are turned off.
2 Plug one end of the serial cable into the Newton InterConnect port (or the
Communication port) on your Newton device (or, if you have a MessagePad 2000,
connect to the Newton Serial Adapter, and then plug the adapter into the Newton
InterConnect port).
Note: If you’re using a MessagePad 2000, be sure to connect the cable to the
serial adapter first and then connect the adapter to your MessagePad 2000—
otherwise, your MessagePad may not establish a connection properly.
If you’re using an eMate 300, you can plug the serial cable into either the
Newton InterConnect port or the serial port.
